    1. Morefilter – Best to Buy for Whirlpool Filter 3 and Maytag

    This filter is a replacement for your own Everydrop Filter 4 for Whirlpool and other Maytag side-by-side refrigerators that are selected. Morefilter is a Californain firm and their filters utilize a renewable, coconut, carbon-block filter that is triggered. Carbon block is a structure having carbon particles that are immovable that guarantees better and more uniform filtration.

    These filters are tested and proven to remove 96 to 99 percent of contaminants, including chlorine, lead, cyst, benzene, and carbofuran. They can last up to 6 months, or 300 gallons of water. 

    Assurity and Certifications 

    These filters carry NSF 42, 53 and 372 certifications, so you should get good tasting, clear water that is largely free of most harmful metal contaminants, herbicides, and parasites.

    Installation and Maintenance 

    WaterDrop filters have an easy twist and lock design mechanism, and clear installation instructions are provided. You need to run water through the system for at least 3 minutes to flush out residue, and the normal flow rate should return after 24 to 36 hours. See the end of our reviews for more details on how to install Whirlpool filters.

    See our reviews for OEM EveryDrop Filter 1 for side-by-side refrigerators and Filter 2 for French door refrigerators— there are no competitive generic replacements for these two filters.

    2. Culligan IC-EZ-1 – Best Inline Refrigerator Water Filter

    If your refrigerator doesn’t have an built-in water filter, then you can use an inline filter which sits between your refrigerator and your water source. For the most part, it’s not possible to bypass your refrigerator’s built-in filter unless it comes with a bypass plug. Culligan independently develops and largely manufactures their products locally in the US. 

    Assurity and Certifications 

    These Culligan filters come in three levels of filtration. This Advanced Filter is NSF 42 and 53 approved and can filter 500 gallons or last for up to 6 months. The Basic Filter is only NSF 42-certified, so will not reduce lead or remove cysts. The higher Premium Filter will do this and reduce additional MTBE (a flammable colorless liquid) and similar volatile organic compounds (VOCs), as well as Mercury.

    Installation and Maintenance 

    This filter comes complete with a built-in mounting bracket and mounting screws, and a cartridge change reminder sticker. It must be installed within 3 feet of your refrigerator, and in a vertical position for optimal flow rate. Flushing takes at least 10 minutes for an ice maker. 

    3. PureLine – Best GE MWF and Kenmore Refrigerator Replacement Water Filter

    Purline is one of the most popular generic filter makers and they independently manufacture their own products, rather than simply rebranding and relabelling. Like most other filters, they use carbon block technology, but layered on top of this are two additional ionization processes to further extract solids and contaminants. One of these processes is electromagnetic absorption which removes the smallest particles. They claim to remove a total of 26 contaminants. 

    Assurity and Certifications 

    Pureline is NSF 42 and 372 certified. They are also WQA certified and this means that all package claims have been independently tested and certified. On their package they claim 99% removal of lead, mercury, chlorine, odor, THM, VOC, herbicides, pesticides, and particles. Additionally, these filters claim a 95% or greater reduction of cadmium, chromium, copper, lindane, and other contaminants. They have a third certification from the IAMPO, so their products carry a high degree of trust and assurity. They make a range of competitive filters for all popular refrigerator brands.

    Installation and Maintenance

    GE filters are quite noticeable and usually located in the top right hand corner of your refrigerator. The general procedure is to gently twist counter clockwise to loosen and take out. The arrow on the new filter should be aligned to the arrow on the filter head, and you just insert and turn clockwise until it stops. Don’t over tighten or force the filter beyond this point, and flush 2 to 3 gallons of water afterwards. 

    4. Morefilter – Best LG LT, ADQ and Kenmore 6990 Refrigerator Water Filter

    LG OEM water filters are some of the most expensive, so people often seek out cheaper alternatives. There are many generic brand alternatives with not much difference between them. We chose to go with WaterDrop because they are a trustworthy distributor, their products check out, and they have a professional and informative website.
